DEVICE FOR MOUNTING ARTIFICIAL PEARLS.

Specification of Letters Patent.

Patented Mar. 18, 1913.

Application filed May 16, 1912. Serial No. 697,796.

To all whom it may concern:

Be it known that we, GUs'rAvE BRUNET and LOUIS APRA, both citizens ofthe Republic of France, and residing, respectively, at Herblay,Department of Seine-et-Oise, and at No. 11 Rue Pastourelle, Paris,France, have invented a new and useful Device for Mounting ArtificialPearls, of which the following is a specification.

The present invention relates to a device for mounting artificial pearlsin such a way as to give great firmness.

The annexed drawing shows by way of example various ways of carrying outthe invention.

Figures 1 and 2 are longitudinal sections. Figs. 3, t and 5 areelevations.

Glass balls (4 are blown so as to have a stem 5 provided at its end withan external excrescence 5 This stem can preferably be recessed towardthe center of the ball so as to assume the position shown in Figs. 1 and2. After the ball has been trimmed by means of suitable materials, ametal closure 0 is set on the stem Z) provided or not near its centerwith a reinforcement cl and traversed throughout its thickness by acentral threaded hole 6 (Fig. 1). In the hole 6 a threaded rod f canthen be screwed, the said rod being secured to a cap 9 of any form whoseedges exactly fit the surface of the glass ball so as to entirelyconceal the method of mounting (Fig. 1). The same way of mounting isemployed in the scarf pin of Fig. 3. This way of mounting is closelyallied to that which is employed for real pearls and presents the sameexternal appearance owing to the fact that the stem is hidden in theinside of the pearl or by the metal cap 9.

In the modified arrangement of Fig. 2 the closure 0 is integral with athreaded metal rod h to provide for other applica-' tions.

Figs. 4 and 5 show two other types of pin according to the invention.One of the pearls is spherical (Fig. 4), the other pear shaped (Fig. 5)and the stems 7) are not recessed toward the interior of the pearl, asin Figs. 2 and 3, and the closures 0 thereof are engaged by the screws fon the caps g of the pins so that when the parts are assembled themounting is hidden by the metal caps g.

It is quite clear that the invention is not limited to the forms ofapplication above mentioned, but that it can be carried out in a numberof various ways that do not alter the principle.

What-we claim and desire to secure by Letters Patent of the UnitedStates of America is:

1. An artificial pearl, comprising an iridescent body having a stem, acap fitting upon the body over the stem, and means for securing the capto the stem.

2. An artificial pearl, comprising a hol low iridescent body having ahollow stem, a closure secured on the stem, a cap fitting over the stem,and means for securing the cap to the stem.

3. An artificial pearl, comprising a hollow iridescent body having ahollow stem lying within the body, a closure secured on the end of thestem, a cap fitting upon the body over the closure, and means forsecuring the cap to the closure.

4. An artificial pearl, comprising a hollow iridescent body having ahollow stem, said stem having a flange at its outer end, the stem beingdepressed toward the center of the body, a closure secured upon thestem, a cap fitting upon the body over the closure, and a screw rodsecuring the cap to the closure.

In an artificial pearl, a hollow iridescent body having a hollow flangedstem,

the stem being depressed toward the center of the body, a closuresecured on the stem, and means secured to the closure for hold ing thepearl.

6. An artificial pearl, comprising a hollow, iridescent body, a portionwhereof is inturned: a metallic mounting for said body portion, having ametallic cap pressed outward to conform in part to the shape of saidbody portion; and an anchor member structurally engaging said inturnedportion and having a threaded extension to engage said metallicmounting.

In testimony whereof we have signed our names to this specification, inthe presence of-two subscribing witnesses.
